Abstract
Provided is a method for producing a joined body obtained by joining a base material A, a film containing an amorphous thermoplastic resin, which is at least one of a thermoplastic epoxy resin and a phenoxy resin, as a main component, and a resin B in this order. The method includes a first joining step of joining the base material A and the film by melting and then solidifying the film in a state in which the film is in contact with the base material A, and a second joining step of joining the base material A and the resin B by melting and then solidifying the film in a state in which the film joined to the base material A is in contact with the resin B. The base material A is at least one of a metal and an inorganic substance, an epoxy equivalent of the amorphous thermoplastic resin is 1,600 g/eq. or more, or the amorphous thermoplastic resin does not contain an epoxy group, and a heat of fusion of the amorphous thermoplastic resin is 15 J/g or less.
